72 PROCEEDINGS OF THE ACADEMY OP 



vestita, thorace latitudine triplo breviore rude punctato, lateribus rotundatis, 

 postice incurvis, medio late excavato, postice utrinque late impresso, elytris 

 thorace angustioribus humeris elevatis; usque ad trientem secundum paulo, dein 

 magis anguatatis et fortiter serratis, striis punctis quadratis fortiter impressis, 

 interstitiis parce subtiliter punctatis, maculis fiavis pluribus ante medium 

 varieconjunctis, alterisque duabus fasciformibus pone medium fere ad suturam 

 extensis, apice saepe gutta flava notato. Long. *33 -47. 



Tej on, numerous. Allied to A. o mat a, but is narrower, and has the 

 punctures of the intervals of the elytra much smaller. The spots are also 

 different, the anterior ones forming a reticulated mass, more or less broken, 

 extending from the base to beyond the middle, and from the margin two- 

 thirds way to the suture. It is also allied to A. o p a c u 1 a Zee, but the sides 

 of the thorax are not yellow, the elytra are less gradually attenuated at tip, 

 and the spots are different. 



43. Acmreodera r e t i f e r , nigro-aenea, subparallela, pilis longis erectis 

 parce vestita, thorace latitudine triplo breviore, punctato, lateribus rotundatis, 

 medio late canaliculato, postice versus angulos oblique profunde impresso, 

 elytris thorace baud angustioribus, ad trientem secundum vix angustatis, dein 

 rotundatim attenuatis, fortiter serratis, striis fortiter punctatis, interstitiis 

 parce subtiliter punctatis, maculis fiavis varie connexis vittam reticulatam 

 fere ad apicem extensam utrinque formantibus. Long. '34. 



One specimen, Tejon. Allied by sculpture and marking to the preceding, 

 but differs by the thorax not being wider than the elytra, by its sides not being 

 suddenly incurved behind, and by the elytra being hardly attenuated from the 

 base to the second third, and finally by the reticulated mass of small spots 

 forming broad vitta extending nearly to the apex. 



44. Acmreodera guttifer, subcylindrica seneo-nigra, parce longe albo- 

 pilosa, thorace latitudine duplo breviore, convexo, lateribus rotundatis, apice 

 transversim impresso, basi medio profunde foveato et late excavato, fortiter 

 punctato, elytris postice obtuse rotundatis, punctis quadratis seriatis, interstitiis 

 subtiliter uniseriatim punctulatis, striis extends exaratis, guttis fiavis ornatis, 

 3 discoidalibus, 5 submarginalibus. Long. -28. 



Tejon. Resembles the small common species of the Atlantic States, but is 

 abundantly distinct ; the anterior discoidal spot is on the 5th and 6th spaces 

 at the middle, the 2d on 4th and 5th at one-fourth from the apex, the 3d 

 on the 3d and 4th half way between the second and the tip : the humeri 

 are elevated. 



45. Limonius hispidus. 



46. Dolopius subustus. A variety of this species having the suture 

 broadly fuscous and the margin of the elytra behind the middle also dark- 

 ened. 



47. Sericosomus d e b i 1 i s , luteo testaceus, elongatus breviter pubescens, 

 thorace latitudine fere duplo longiore, lateribus late rotundatis, antrorsum 

 vix angustiore, angulis posticis subcarinatis haud divaricatis, dense punctato, 

 obsolete canaliculato, elytris striis punctatis, interstitiis subconvexis confertim 

 punctulatis. Long. - 29. 



One specimen Tejon. Closely related to S. silaceus (El. silaceus Say,) 

 and differs essentially only by the posterior angles of the thorax not diverging, 

 but continuing the outline of the sides of the thorax.

48. Elater cordifer, niger, breviter pubescens, thorace opaco, confer- 

 tissime punctato, latitudine paulo longiore, antrorsum sensim angustato, late- 

 ribus rotundatis, elytris lsete auruntiacis, macula communi nigra apicali cor- 

 diformi signatis, striis punctatis, interstitiis planis rugose punctulatis, antennis 

 articulis 2ndo et 3io conjunctis 4to vix longioribus ; tarsis fuscis. Long. -41.
